Geological Background

Jabal el-Marha is an isolated ca. 2500-m-high, crescent-shaped tuff cone about 11 km south of the center of Sana'a, the capital city of Yemen. A very fresh-looking basaltic aa lava flow was erupted from this little-known volcano (Catalog of Active Volcanoes of the World), although the age of the flow is not known. The flow traveled 1.8 km east from the cone over alluvial deposits on a broad plain that is partly covered with bombs and lapilli from the eruption.
